10-5. Comparison Output Pattern
The two types of judgment output operation are Standard
Output and Area Output.
In these examples, the judgment output behavior is for when
the Comparison Pattern Setting is “1” (OK/LO/HI).
10-5-1. Standard Output
Judgment output operation is as follows.
(when hysteresis is “0”)
HI: high limit value < indicator value
LO: low limit value < indicator value
OK: indicator value < low limit value
OFF

NOTE
Judgment output operation changes according to the hystere-
sis setting. See “10-4. Hysteresis” on page 47.
10-5-2. Area Output
Judgment output operation is as follows.
(when hysteresis is “0”)
HI: high limit value < indicator value
LO: Low limit value < indicator value < high limit value
OK: indicator value < low limit value

10-6. Nearly Zero
Set the range in which indicator values are evaluated as being
nearly zero.
NOTE
Nearly Zero judgment results are closely related to high limit
and low limit judgment output.
See “10-3. Comparison Mode Setting” on page 46 for details.
